I am a new blackberry 7100t (t mobile) owner and I setup the BWC to read via POP from an exchange account I have at a host (1and1).

It works fine, but whenever the BWC queries to get email from the exchange server, my outlook client marks the message as read. I understand why it thinks it should do this as something external to exchange did pull the email, but I would like to prevent the emails from being marked read. I would like to see my unread emails as unread even though they were forwarded to my blackberry.

This is more a workaround than a solution, but can you set up your mailbox at 1and1 to forward copies to your BWC account?

I actually tried this, and I love the speed, but here is my issue. When my colleague sends me exchange email, it does not route through my domain.com, it goes from exchange to exchange, thus never gets fwd'd to my BB.
